Sentry Plus Sound Volume

I just setup a new Sentry Plus Security Camera with a solar panel. It was updated to the latest firmware, v. 1.1.0 . When I turn on the sound the volume level is very, very low. I made sure both my iPhone and iPad volumes were turned up to maximum. When I select the sound option in Netvue app, ir appears there are only audio settings. How do you turn up the sound volume on a Sentry Plus?

Sorry for the late reply.
Sorry there is no setting to turn up the volume of live feed.
